"hating someone just for the sake of nothing would be unfair to this clueless fellow. i try to avoid that coz the feeling of being cursed by someone isnt good."

I'd agree on the basic point, however usually we hate the people for a reason, but we don't quite know why. Usually its' a feeling we get, call it intuition or something, maybe its something we can smell, or something we notice without noticing...but there's usually a reason. Not an obvious one, but none the less.
I hear what you're saying about judging a book before you've read it, I myself prefer to "read a little" as it were before passing judgement, but usually I at least pay attention to my gut feeling - its rarely steered me wrong. Then again I'm happy to admit I'm wrong!

=S not really, I dont hate anyone, Its hard to to hate people, especially if I dont know them

But! I can name one I have felt dislike for out of pointless Jealousy( that god Im out of that stage >___<)
